About Blackrock Caverns

Rumors suggest that Deathwing himself carved out the subterranean labyrinth that allows the Twilight's Hammer to secretly transport elementals from the majestic Mount Hyjal to Blackrock Mountain. A vital hub of this shadow network is Blackrock Caverns, site of the cult's blistering forge and some of its most heinous experiments, including the transformation of cultists into twilight dragonkin.

From the in-game Adventure Guide.

An easy achievement after a new strat I developed.

Setup we used:
Feral DPS (Speced Bear) - Me
Prot Warrior
Resto Shaman
Destruction Warlock
Ret Pally

Edit: (v4.3) Off tanks for Corla can be anything from a hunter pet to a rogue. Interrupts keep fears off the healer, so whoever is tanking should be able to. No dedicated tank needed! Shes a pushover.

Begin by clearing adds past the boss down to the next boss. When you get to the ramp going down, clear the next dragonkin pat.

Now begin by setting up your OT, in this scenario it was me the feral druid, by standing half way to the ramp that leads to next boss. Youll be somewhat near a broken cart and a tent. Have your healer stand between you and the zealots. You should be farther than 40 yards from the zealots but not out of range of heals.

Now that you have your positions set up. Have your dps and MT decide who's going to block the two beams. Set up someone to be on backup as well in case of fears. (Which should be interrupted by the OT anyways)

Have the OT pull the boss back to the position, away from the adds. Now when one evolves, they wont get the 100% haste aura she gives within 40 yards.

Tanks wont get crushed, and healers wont go oom. Relax between add kills in case you need to get mana.

Hard achievement made lulzy.

TL;DR --- 2 Tanks Separate the boss from adds by more than 40 yards to negate her haste aura.
